String of Dolphin, whose scientific name is Senecio Peregrinus, might be the cutest succulent in existence. It’s a rare animal-like variety that develops some beautiful curvy leaves, which perfectly resemble a pod of little jumping Dolphins. And like other “String of” plants such as hearts, bananas, turtles, and pearls, String of Dolphins is a cross-pollination of Senecio Rowleyanus (String of Pearls) and Senecio Articulatus (hot dog cactus). It can grow up to 3 ft long and 15 cm (6 inches) tall, which makes it look great spilling out of a hanging basket or trickling down over bookshelves or even on the edge of a stair rail.
